The goal of this analysis is to devise a “complete communities” methodology and report on its application to a sub-geography in the Bay Area. For our analysis, we first filtered to the points of interest in Alameda county, and then narrowed that down into the points of interest in Oakland. We chose Oakland because of its size; we were curious to see how amenity access differs across such a large area and if income would have a significant play in equitable access.
First, we loaded in the OpenStreetMap points of interest data downloaded from Geofabrik (located on the shared G drive).
Map of the points of interest in Alameda County:
We selected five points of interest (POI) out of the 129 POI types available. For this analysis, the points of interest we considered to be essential for a “complete community” include parks, supermarkets, hospitals, and schools.
We also viewed waste water plants as a negative utility, with the expectation that most residents would not want a waste water plant near their homes. This also relates to the income category angle of this analysis in seeing if waste water plants were closer to areas of lower income compared to those of higher income (to be explored in the equity analysis below).
Map of the points of interest specified in Alameda County (parks, supermarkets, hospitals, schools, waste water plants):
Upon initial inspection, it is interesting to note that the wastewater plants are primarily found on the west side of Oakland, nearest to the Bay and are not found in inner areas of the city.
Then, we narrow down to East Oakland block groups, which have the highest percentage of BIPOC and working class tracts (traditionally further from amenities).
